A 1940s Island at War event will be held on the steam railway this weekend (August 20 and 21).
Anyone dressing appropriately for the era will receive half price travel on trains leaving Douglas and Port Erin at 9.50am, 11.50am, 1.50pm, 3.50pm and 5.30pm.
The Island at War experience will begin at Douglas Station which will be transformed into a military outpost from World War II.
The 'Home Guard' will issue papers before passengers travel to Port St Mary for a 1940s agricultural display and onto Port Erin for a VE Day tea party and other sights and sounds of the era.
A spokesman said passengers are urged to ensure their papers are in order or risk arrest. Likewise they are warned to watch out for spies!
Community Culture and Leisure Minister David Cretney MHK said: "You could spend a whole day taking in the various aspects of the Island At War event.
"I would urge people to allow plenty of time to absorb all the attractions at Douglas Station before taking the steam train south.
"Here you will be able to enjoy drills, demonstrations and children's workshops run by Second World War military medical, Royal Navy, RAF and Home Guard personnel.
"There are also planned displays of beautifully restored period vehicles, both military and civilian, plus a big swing band playing in the afternoons."
In addition modern money can be exchanged for 1940s currency – pennies, hapennies thrupenny bits, tanners and shillings – at the money exchange.
The railway booking offices in Douglas and Port Erin plus the Tickethall in Douglas and the Whistlestop Tea Party and WI stall in Port Erin will all accept both modern day and 1940s currency.
A shuttlebus will be available at Ballasalla Station to take passengers to the Manx Aviation and Military Museum which incorporates the Museum of the Manx Regiment.
The museum will be hosting wartime radio demonstrations with the Royal Air Force and the Royal Signals Amateur Radio Society.
Mr Cretney added: "The Island At War weekend has been made possible with the support of many organisations and individuals, some of whom are voluntarily bringing their skills, expertise or artefacts to make it an authentic war time experience.
"My department is extremely grateful to everyone involved. Hopefully, it will be a pleasant journey down memory lane for some and a fascinating glimpse into the past for younger generations."
Special Heritage Railways' letter stamps and covers will be available to commemorate the Island At War weekend.
They can only be bought at the weekend from Douglas and Port Erin stations.
Half price travel on the train for those in 1940s costume means an adult can board at the Home Guard's military base in Douglas, be issued with ID papers for travel to Port St Mary, see the agricultural display, then go onto Port Erin for the VE Day tea party, before returning to Douglas to catch some live swing music, all for £5.80.
Concessions apply and train travel is free for resident ticket holders.
An extra train will be providing shuttle runs between Port Erin and Port St Mary.
This service will depart in between the regular timetabled services and is free to those with any steam train tickets, valid for the day of travel. Regular fares apply for those without.
The times of the additional trains are 10.50am, 11.20am, 1pm, 1.20pm, 3pm and 3.20pm.
